' chiefly to facilitate building operations in the construction of wallsof plastic material, same being'of such formation as to enable the bodyportion of the wall to be of coarse or poor material and the facing tobe rich or of fine material to present a good, substantial, and durablefinish. r v

A further purpose is the provision of a hopper readily adjustable todifferent thicknesses of wallsand which will withstand the hard usage towhich it will be subjected in operation. The hopper is partitioned toseparate the difierent materials, the partitions projecting a distancebelow the hopper to keep the said materials apart except for properbonding essential to form a homogeneous wall.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a 'view of the hopper as seen from the front end. Fig. 2 is a viewfrom the rear end, the section-lines showing the form upon whichsameisfmounted. .Fig. 3 isatop plan view, the intermediate portion beingbroken away. Fig. tie a side elevation.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The hopper may be of any length and width and is of rectangularformation in plan view, the ends preferably being parallel and verticaland the sides upwardly flared. The several parts are preferablyconstructed of metal,

same being reinforced wherever required to strengthen and stiflen thewalls.

The sides 1 and 2 are provided at their ends with inner flanges 2forming stops to prevent outward displacement of the ends. The flanges 2are an integral part of the sides and are formed by bending end portionsthereof at a right angle. Angle-irons 3 are secured to the sides 1adjacent to their flanged ends and are spaced from flanges 2 a distancecorresponding to the thickness of the ends of the hopper for receptionthereof. The parts 2 and 3 constitute guides or stops for embracing edgeportions of the ends and securing the latter from either outward orinward displacement. The parts 2 and 3 also constitute reinforcements,as will be readily comprehended.

The ends 4 and 5 of the hopper may be of any width corresponding to thethickness of wall to be constructed, and their edge portions are fittedbetween the stops or guides 2 and 3. The bottom edge of the end 5 ispreferably straight, whereas the corresponding edge of the end 4 isconcave or hollow to admit of readily clearing the portion of wallconstructed when shifting the hopper to a new position. The upper edgesof the ends 4: and 5 are convex or upwardly curved, thereby admitting ofkeeping the material between the sides. The edges of the ends areupwardly sloped, corresponding to the upward flare of the sides of thehopper, thereby admitting of a gradual compacting of the mate rial inits descent through the hopper to the form.

1 Longitudinal partitions 6 and 7 subdivide the hopper, so as to formspaces 8, 9, and 10 for reception of the difierent grades of material.The end portions of the partitions are bent at a right angle to formflanges 11,which receive the boltsor other fastenings 12, connecting thepartitions to the end supports. One of the longitudinal partitions, as7, terminates a distance from the end at of the hoppeer and is connectedto a transverse partition 13, which forms with the end 4 a space 14 forreceiving the material forming the facing of an opening orreturn at thecorners of walls. The inner end of the transverse partition 13 is bentto form a flange 15, which is secured by fastenings 12 to thelongitudinal partition 6, the outer end being received between stops orguides 16, secured to and extended in from the side 2. Said stops orguides 16 arewings or parts of angle-irons attached to the side 2 andspaced apart a distance to snugly receive the outer end of partition 13.The outer edge of partition 13 slopes to correspond with the inclinationof the corresponding edges of parts 4 and 5, and said partition, likethe ends 4 and 5, will be provided in different widths to adapt thehopper for different thicknesses of walls.

Diagonal braces connect the sides 1 and 2 at their ends and involve asectional construction to admit of lengthening and shortening thebraces, according as the sides of the hopper are to be separated orbrought together. The braces are indicated at 17 and are composed ofcompanion bars pivotally connected at their ends to the corners of therespective sides, said bars being longitudinally slotted, as shown at18, and receiving a bolt or fastoning 19 at the point of crossing, saidfastening passing through the slots of the four bars. The companion barsof the respective braces are alternately arranged and are spaced apartat their pivotal ends by means of washers 20, slipped upon thepivot-fastenings 21 and arranged between said bars. This construction isshown most clearly in Figs. 3 and 4, which indicate the two bars of eachbrace spaced apart, with one bar of each set or pair of bars passedthrough the space formed between the bars of the other set or pair,thereby resulting in the alternate arrangement herein described. Byloosening the bolts or fastenings 19 the sides 1 and 2 may be separatedor brought together and when properly positioned are made secure byretightening the fastenings 19.

Angle-bars 22 are rigidly attached to the lower edge portions of thesides 1 and 2 and serve the double purpose of stiffening andstrengthening same, besides forming a support for wheels 23, which areadapted to travel upon the upper edge of the form 24. After the form hasbeen set up the hopper is placed thereon about as indicated in Fig. 1and is shifted by being moved upon the wheels 23. The several partitionsproject below the walls of the hopper, so as to enter the space inclosedby the form to an extent to insure proper separation of the differentkinds of material. It is to be understood that the hopper is movedbefore the material sets. Hence the filling and the facing materials areenabled to come together to form a bond, Whereby the wall is, ineffect,'homogeneous. The poor material is supplied to the space 9 andthe facing material to the spaces 8, 10, and 14. By reason of theextension of the partitions into the space of the form the differentkinds of materials may be supplied to the hopper at different times, themixing being prevented by the pendent portions of the partitions, aswill be readily comprehended. The hopper is removed before the materialsets; hence same can settle so as to unite and form, in effect, a singlesolid wall comprising a central portion of coarse or poor material andan outer portion of fine rich material.

The sides of the hopper may extend parallel, if desired; but it ispreferred to have them upwardly flared. By having the lower edge of therear wall 4 upwardly curved sufficient material is left after the hopperis moved forward so as to come level with the form after being tamped.

Having thus described the invention, what is claimed as new is 1. Ahopper comprising side and end walls, the side walls being provided attheir ends with spaced stops or guides to receive and embrace edgeportions of the end walls, and means for connecting the side walls,substantially as set forth.

2. A hopper for the purpose described comprising end and side walls, theside walls having their end portions bent inward to form stops orguides, other stops secured to the side walls adjacent to their bentends to form cooperating stops or guides for reception of the edgeportions of the end walls, and means for connecting said side walls,substantially as described.

3. A hopper comprising end and side walls, guides at the ends of theside Walls for reception of the edge portions of the end walls, andbraces connecting the side walls and having a diagonal arrangement andpivoted at their ends to the corners of the side walls and firmlysecured at the point of crossing, substantially as set forth.

4. A hopper comprising side and end walls, diagonally-arranged bracesconnecting the side walls, each set of braces comprising slottedcompanion bars pivoted at their outer ends to the respective cornerportions of said sides, the bars of corresponding braces having analternate arrangement, and a fastening connecting the several bars ofthe braces at the point of crossing, substantially as set forth.

5. A hopper for the purpose set forth comprising separated spaces, onefor reception of poor or coarse material and the othertfor reception ofrich or fine material to form a facing to the body formed by the poormaterial, substantially as specified.
